4 types of tissue
Epithelial
Connective
Muscular
Nervous
Epithelial tissue
Covers body surfaces and lines hollow organs, body cavities, ducts, and forms glands
Connective tissue
Protects, supports, and binds organs
Stores energy as fat, provides immunity
Muscular tissue
Generates the physical force needed to make body structures move and generate body heat
Nervous tissue
Detects changes in body and responds by generating nerve impulses
Simple squamous
Filtration
Simple cuboidal
Secretion, absorption
Stratified squamous
Protection from abrasion/UV/foreign invasion, prevent h2o loss
Stratified cubodial
Protection, excretion/absorption
Stratified columnar
Protection, secretion
Nonciliated simple columnar
Secretion, absorption, microvilli increase surface area. Goblet cells secrete mucus
Ciliated simple columnar
Moves materials such as mucus or an egg
Nonciliated pseudostratified columnar
Absorption, secretion
Ciliated pseudostratified columnar
Secretion, moved mucus
Transitional epithelium
Allows stretching
Endocrine
Release hormones into the interstitial fluid which then diffuses into the blood stream
Exocrine
Secrete products into ducts which empty onto surface of a covering and lining epithelium, avoiding the bloodstream
Connective tissue functions
Binds tissue together Supports and strengthens tissue Protects and insulates internal organs Compartmentalize and transport Energy reserves and immune responses
Cartilage
Dense network of collagen divers and elastic divers firmly embedded in ground substance. Dense regular connective tissue
Bones
Organs composed of several different connective tissue: bone tissue; periosteum and endosteum
Blood and lymph
Connective tissue with liquid and extra cellular matrix
Membranes
Flat sheets that cover or line a part of the body
Epithelial membrane include
Mucous
Serous
Cutaneous
Synovial
Meninges
Membranes that line the brain and spinal cord made up of only connective tissue
Muscular tissue
Consist of elongated cells called muscle fibres or myocytes that use ATP to generate force
Types of muscular tissue
Skeletal
Cardiac
Smooth
Nervous tissue
In charge of communication
Consists of neutrons and neurogila
Neuron
Consists of dendrites, cell body and axon
Conducts nerve impulses along cell membrane
Neurogila
Support, protect, nourish the neurons
What tissue regenerates
Epithelial and connective
When will scar tissue form
If the damage tissues affects the stroma. Fibroblast will sectete collagen and ground substance
When tissue damage is extensive…
Parenchymal and fibroblasts are in active repair
Fibroblasts divide rapidly, new collagen fibres are made, new blood capillaries supply material
Histology
The science that deals with the study of tissues
Fibroblasts
Main cells of connective tissue. Scretes the EMC and play a role in tissue healing
Adipocyte
Cells of loose adipose CT. They provide padding and protection
Parenchyma
Cells of an organ that constitute the functioning part of that organ. Specialized for a specific organ
Stroma
Supportive CT that supports and/or surrounds the parenchymal tissue
